The computer music soundtrack was composed using many eclectic sound sources from the real world that may at once seem familiar to the listener. The interactive video projection, which processes and manipulates the live images of the dancers (being shot from the theater catwalks), uses software designed specifically for dance. The video processing itself is controlled by signals sent from the software playing the music and is therefore often linked rhythmically. In addition, the movement of the dancers, such as their speed or position on the stage effects the video processing.
